HYDRAULIC PRESS.

SPECIFICATION forming part of Letters Patent No. 479,317, dated July 19, 1892.

Application filed October 17, 1891. Serial No. 409,077. (No model.)

To all whom it may concern:

Be it known that I, JOHN F. TAYLOR, of Test Park, in the county of Ulster and State of New York, have invented a new and Improved Hydraulic Press, of which the following is a full, clear, and exact description.

- The invention relates to hydraulic presses; and its object is to provide certain new and useful improvements in hydraulic presses designed for use in compressing cotton bales or other articles under very heavy pressure, the necessary resistance being furnished in a very simple and inexpensive manner and without relying on tensile strength of rods and links.

The invention consists of a supported weight carrying the platen.

The invention also consists in certain parts and details and combinations of the same, as will be hereinafter fully described, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure 1 is a side elevation of the improvement with parts in section, and Fig. 2 is a sectional plan View of the same on the line as a: in 1.

The improved hydraulic press is provided with a suitably-constructed base A,on which is erected the hydraulic cylinder or cylinders B B, carrying the lower platen 0, located opposite the upper platen D, and between which platens the bale is held to be compressed. The upper platen D is secured on the under side of a vessel E of considerable size and adapted to be filled with an inexpensive but heavy material, so as to form a bulkhead or immovable platen, the weight of which is sufiiciently heavy to meet all resistance required in working the press.

The vessel E is supported in a suitable manner, preferably by being provided with a bottom F, supported on columns G, resting on the base-plate A. On the bottom F is secured or formed integral with it the platen D. It will be seen that a resistance constructed in this manner can be increased to any desired degree, so as to meet all requirements as to the strength of the hydraulic press to permit com pressing the bale up to and above three thousand tons, if desired. It will thus be seen that the resistance does not rely on the tensile strength of rods, braces, bars, and the like, as is the case in baling-presses as now constructed.

It will further be seen that the baling-press can be constructed very cheaply, as the material to fill the vessel E can be of any inexpensive kind. The vessel E is preferably globe-shaped, as plainly shown in Fig. 1.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. A compress comprising vertical supports, a weight mounted on said supports and carrying the upper platen on its under side, and the vertically-movable piston having a platen on its upper end, the said weight being sufficient to wholly withstand any pressure that the piston may exert, thereby relieving said supports from tensile strain, substantially as described.

2. The herein-described compress, comprising vertical supports, a weight-receiving receptacle mounted on said supports and adapted to contain a sufficient weight to withstand any pressure that the piston may exert without exerting any tensile strain on said supports, an upper platen on the bottom of the vessel between the supports, and a hydraulic piston on the base between the supports and carrying the lower piston, substantiallyas described.

JOHN F. TAYLOR.
